Check Digit Verification of cas no
The CAS Registry Mumber 912277-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,2,2,7 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 912277-31:
(8*9)+(7*1)+(6*2)+(5*2)+(4*7)+(3*7)+(2*3)+(1*1)=157
157 % 10 = 7
So 912277-31-7 is a valid CAS Registry Number.
