Check Digit Verification of cas no
The CAS Registry Mumber 135257-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135257-77:
(8*1)+(7*3)+(6*5)+(5*2)+(4*5)+(3*7)+(2*7)+(1*7)=131
131 % 10 = 1
So 135257-77-1 is a valid CAS Registry Number.
