221012-02-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221012-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,1 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221012-02:
(8*2)+(7*2)+(6*1)+(5*0)+(4*1)+(3*2)+(2*0)+(1*2)=48
48 % 10 = 8
So 221012-02-8 is a valid CAS Registry Number.
