Check Digit Verification of cas no

The CAS Registry Mumber 74212-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,1 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74212-69:
(7*7)+(6*4)+(5*2)+(4*1)+(3*2)+(2*6)+(1*9)=114
114 % 10 = 4
So 74212-69-4 is a valid CAS Registry Number.
