Check Digit Verification of cas no
The CAS Registry Mumber 773136-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,1,3 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 773136-70:
(8*7)+(7*7)+(6*3)+(5*1)+(4*3)+(3*6)+(2*7)+(1*0)=172
172 % 10 = 2
So 773136-70-2 is a valid CAS Registry Number.
