163231-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163231-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,2,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 163231-33:
(8*1)+(7*6)+(6*3)+(5*2)+(4*3)+(3*1)+(2*3)+(1*3)=102
102 % 10 = 2
So 163231-33-2 is a valid CAS Registry Number.
