Check Digit Verification of cas no
The CAS Registry Mumber 77729-69-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,2 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77729-69:
(7*7)+(6*7)+(5*7)+(4*2)+(3*9)+(2*6)+(1*9)=182
182 % 10 = 2
