213821-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213821-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,2 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213821-73:
(8*2)+(7*1)+(6*3)+(5*8)+(4*2)+(3*1)+(2*7)+(1*3)=109
109 % 10 = 9
So 213821-73-9 is a valid CAS Registry Number.
