1229621-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1229621-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,6,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1229621-40:
(9*1)+(8*2)+(7*2)+(6*9)+(5*6)+(4*2)+(3*1)+(2*4)+(1*0)=142
142 % 10 = 2
So 1229621-40-2 is a valid CAS Registry Number.
