Check Digit Verification of cas no

The CAS Registry Mumber 1572-51-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1572-51:
(6*1)+(5*5)+(4*7)+(3*2)+(2*5)+(1*1)=76
76 % 10 = 6
So 1572-51-6 is a valid CAS Registry Number.

Nucleophile-Catalysed Additions of Aldehydes and Ketones to Acrylic Compounds: The Effectiveness of High Pressures

Hill, Jon S.,Isaacs, Neil S.

, p. 2641 - 2676 (2007/10/02)

The preparation of a wide range of compounds of general type: CH2=C(Z)-CR1R2OH (Z = CN, COOR, CHO,; R1,R2 = H, alkyl, aryl) from the reaction of CH2=CHZ with aldehydes and ketones, is effectively catalysed by tertiary amines especially DABCO.Rates are found to be very strongly accelerated by high pressures (2-10 kbar) which alone permits the additions of ketones or of crotonic acid derivatives to take place.In the absence of carbonyl acceptors novel oligomers of acrylic compounds form.
