157117-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157117-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,1 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157117-12:
(8*1)+(7*5)+(6*7)+(5*1)+(4*1)+(3*7)+(2*1)+(1*2)=119
119 % 10 = 9
So 157117-12-9 is a valid CAS Registry Number.
