18377-52-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18377-52-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18377-52:
(7*1)+(6*8)+(5*3)+(4*7)+(3*7)+(2*5)+(1*2)=131
131 % 10 = 1
So 18377-52-1 is a valid CAS Registry Number.
