129529-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129529-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,2 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129529-19:
(8*1)+(7*2)+(6*9)+(5*5)+(4*2)+(3*9)+(2*1)+(1*9)=147
147 % 10 = 7
So 129529-19-7 is a valid CAS Registry Number.
