Check Digit Verification of cas no
The CAS Registry Mumber 1226910-30-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,9,1 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1226910-30:
(9*1)+(8*2)+(7*2)+(6*6)+(5*9)+(4*1)+(3*0)+(2*3)+(1*0)=130
130 % 10 = 0
So 1226910-30-0 is a valid CAS Registry Number.
