129743-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129743-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129743-74:
(8*1)+(7*2)+(6*9)+(5*7)+(4*4)+(3*3)+(2*7)+(1*4)=154
154 % 10 = 4
So 129743-74-4 is a valid CAS Registry Number.
