131157-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131157-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131157-77:
(8*1)+(7*3)+(6*1)+(5*1)+(4*5)+(3*7)+(2*7)+(1*7)=102
102 % 10 = 2
So 131157-77-2 is a valid CAS Registry Number.
