Check Digit Verification of cas no
The CAS Registry Mumber 207974-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,9,7 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 207974-13:
(8*2)+(7*0)+(6*7)+(5*9)+(4*7)+(3*4)+(2*1)+(1*3)=148
148 % 10 = 8
So 207974-13-8 is a valid CAS Registry Number.
