147486-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147486-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,4,8 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 147486-88:
(8*1)+(7*4)+(6*7)+(5*4)+(4*8)+(3*6)+(2*8)+(1*8)=172
172 % 10 = 2
So 147486-88-2 is a valid CAS Registry Number.
