37891-39-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 37891-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,9 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 37891-39:
(7*3)+(6*7)+(5*8)+(4*9)+(3*1)+(2*3)+(1*9)=157
157 % 10 = 7
So 37891-39-7 is a valid CAS Registry Number.
