129779-51-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129779-51-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,7 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129779-51:
(8*1)+(7*2)+(6*9)+(5*7)+(4*7)+(3*9)+(2*5)+(1*1)=177
177 % 10 = 7
So 129779-51-7 is a valid CAS Registry Number.
