133988-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133988-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,8 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133988-97:
(8*1)+(7*3)+(6*3)+(5*9)+(4*8)+(3*8)+(2*9)+(1*7)=173
173 % 10 = 3
So 133988-97-3 is a valid CAS Registry Number.
