Check Digit Verification of cas no
The CAS Registry Mumber 774229-27-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,2,2 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 774229-27:
(8*7)+(7*7)+(6*4)+(5*2)+(4*2)+(3*9)+(2*2)+(1*7)=185
185 % 10 = 5
So 774229-27-5 is a valid CAS Registry Number.
