219972-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219972-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219972-20:
(8*2)+(7*1)+(6*9)+(5*9)+(4*7)+(3*2)+(2*2)+(1*0)=160
160 % 10 = 0
So 219972-20-0 is a valid CAS Registry Number.
