Check Digit Verification of cas no
The CAS Registry Mumber 10130-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,3 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10130-29:
(7*1)+(6*0)+(5*1)+(4*3)+(3*0)+(2*2)+(1*9)=37
37 % 10 = 7
So 10130-29-7 is a valid CAS Registry Number.
