333742-34-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 333742-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,7,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 333742-34:
(8*3)+(7*3)+(6*3)+(5*7)+(4*4)+(3*2)+(2*3)+(1*4)=130
130 % 10 = 0
So 333742-34-0 is a valid CAS Registry Number.
