249642-32-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249642-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,6,4 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 249642-32:
(8*2)+(7*4)+(6*9)+(5*6)+(4*4)+(3*2)+(2*3)+(1*2)=158
158 % 10 = 8
So 249642-32-8 is a valid CAS Registry Number.
