213921-66-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213921-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,9,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 213921-66:
(8*2)+(7*1)+(6*3)+(5*9)+(4*2)+(3*1)+(2*6)+(1*6)=115
115 % 10 = 5
So 213921-66-5 is a valid CAS Registry Number.
