129147-77-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129147-77-9 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 129147-77:
(8*1)+(7*2)+(6*9)+(5*1)+(4*4)+(3*7)+(2*7)+(1*7)=139
139 % 10 = 9
So 129147-77-9 is a valid CAS Registry Number.
