215253-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215253-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,2,5 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 215253-33:
(8*2)+(7*1)+(6*5)+(5*2)+(4*5)+(3*3)+(2*3)+(1*3)=101
101 % 10 = 1
So 215253-33-1 is a valid CAS Registry Number.
