1345837-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1345837-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,8,3 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1345837-40:
(9*1)+(8*3)+(7*4)+(6*5)+(5*8)+(4*3)+(3*7)+(2*4)+(1*0)=172
172 % 10 = 2
So 1345837-40-2 is a valid CAS Registry Number.
