Check Digit Verification of cas no
The CAS Registry Mumber 1474-78-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1474-78:
(6*1)+(5*4)+(4*7)+(3*4)+(2*7)+(1*8)=88
88 % 10 = 8
So 1474-78-8 is a valid CAS Registry Number.
