293745-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 293745-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,4 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 293745-33:
(8*2)+(7*9)+(6*3)+(5*7)+(4*4)+(3*5)+(2*3)+(1*3)=172
172 % 10 = 2
