3Check Digit Verification of cas no
The CAS Registry Mumber 76930-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,3 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 76930-14:
(7*7)+(6*6)+(5*9)+(4*3)+(3*0)+(2*1)+(1*4)=148
148 % 10 = 8
So 76930-14-8 is a valid CAS Registry Number.
