The CAS Registry Mumber 1262844-01-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,4 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1262844-01:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*4)+(3*4)+(2*0)+(1*1)=148
148 % 10 = 8
So 1262844-01-8 is a valid CAS Registry Number.
