153716-46-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153716-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,1 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 153716-46:
(8*1)+(7*5)+(6*3)+(5*7)+(4*1)+(3*6)+(2*4)+(1*6)=132
132 % 10 = 2
So 153716-46-2 is a valid CAS Registry Number.
