Check Digit Verification of cas no
The CAS Registry Mumber 1021187-29-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,8 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1021187-29:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*8)+(3*7)+(2*2)+(1*9)=100
100 % 10 = 0
So 1021187-29-0 is a valid CAS Registry Number.
