Check Digit Verification of cas no
The CAS Registry Mumber 1262287-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,8 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1262287-07:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*8)+(3*7)+(2*0)+(1*7)=149
149 % 10 = 9
So 1262287-07-9 is a valid CAS Registry Number.
