129156-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129156-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129156-88:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*6)+(2*8)+(1*8)=143
143 % 10 = 3
So 129156-88-3 is a valid CAS Registry Number.
