221082-64-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221082-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,8 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 221082-64:
(8*2)+(7*2)+(6*1)+(5*0)+(4*8)+(3*2)+(2*6)+(1*4)=90
90 % 10 = 0
So 221082-64-0 is a valid CAS Registry Number.
