129760-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129760-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,6 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129760-16:
(8*1)+(7*2)+(6*9)+(5*7)+(4*6)+(3*0)+(2*1)+(1*6)=143
143 % 10 = 3
So 129760-16-3 is a valid CAS Registry Number.
