Check Digit Verification of cas no
The CAS Registry Mumber 218916-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,1 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 218916-77:
(8*2)+(7*1)+(6*8)+(5*9)+(4*1)+(3*6)+(2*7)+(1*7)=159
159 % 10 = 9
So 218916-77-9 is a valid CAS Registry Number.
