129147-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129147-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,4 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129147-70:
(8*1)+(7*2)+(6*9)+(5*1)+(4*4)+(3*7)+(2*7)+(1*0)=132
132 % 10 = 2
So 129147-70-2 is a valid CAS Registry Number.
