29913-86-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29913-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,1 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 29913-86:
(7*2)+(6*9)+(5*9)+(4*1)+(3*3)+(2*8)+(1*6)=148
148 % 10 = 8
So 29913-86-8 is a valid CAS Registry Number.
