151491-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151491-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,4,9 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 151491-88:
(8*1)+(7*5)+(6*1)+(5*4)+(4*9)+(3*1)+(2*8)+(1*8)=132
132 % 10 = 2
So 151491-88-2 is a valid CAS Registry Number.
