157561-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157561-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,6 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157561-30:
(8*1)+(7*5)+(6*7)+(5*5)+(4*6)+(3*1)+(2*3)+(1*0)=143
143 % 10 = 3
So 157561-30-3 is a valid CAS Registry Number.
