292871-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 292871-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,2,8,7 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 292871-35:
(8*2)+(7*9)+(6*2)+(5*8)+(4*7)+(3*1)+(2*3)+(1*5)=173
173 % 10 = 3
So 292871-35-3 is a valid CAS Registry Number.
