21377-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21377-44-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,7 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21377-44:
(7*2)+(6*1)+(5*3)+(4*7)+(3*7)+(2*4)+(1*4)=96
96 % 10 = 6
So 21377-44-6 is a valid CAS Registry Number.
