Check Digit Verification of cas no
The CAS Registry Mumber 1572-11-8 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, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1572-11:
(6*1)+(5*5)+(4*7)+(3*2)+(2*1)+(1*1)=68
68 % 10 = 8
So 1572-11-8 is a valid CAS Registry Number.
