129157-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129157-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129157-13:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*7)+(2*1)+(1*3)=127
127 % 10 = 7
So 129157-13-7 is a valid CAS Registry Number.
