Check Digit Verification of cas no
The CAS Registry Mumber 133814-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,1 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133814-77:
(8*1)+(7*3)+(6*3)+(5*8)+(4*1)+(3*4)+(2*7)+(1*7)=124
124 % 10 = 4
So 133814-77-4 is a valid CAS Registry Number.
