129953-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129953-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,5 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129953-23:
(8*1)+(7*2)+(6*9)+(5*9)+(4*5)+(3*3)+(2*2)+(1*3)=157
157 % 10 = 7
So 129953-23-7 is a valid CAS Registry Number.
