193471-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193471-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,7 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 193471-33:
(8*1)+(7*9)+(6*3)+(5*4)+(4*7)+(3*1)+(2*3)+(1*3)=149
149 % 10 = 9
So 193471-33-9 is a valid CAS Registry Number.
