157557-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157557-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,5 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157557-36:
(8*1)+(7*5)+(6*7)+(5*5)+(4*5)+(3*7)+(2*3)+(1*6)=163
163 % 10 = 3
So 157557-36-3 is a valid CAS Registry Number.
