133729-62-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133729-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,2 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133729-62:
(8*1)+(7*3)+(6*3)+(5*7)+(4*2)+(3*9)+(2*6)+(1*2)=131
131 % 10 = 1
So 133729-62-1 is a valid CAS Registry Number.
