20641-27-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20641-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20641-27:
(7*2)+(6*0)+(5*6)+(4*4)+(3*1)+(2*2)+(1*7)=74
74 % 10 = 4
So 20641-27-4 is a valid CAS Registry Number.
