Check Digit Verification of cas no
The CAS Registry Mumber 1326-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1326-85:
(6*1)+(5*3)+(4*2)+(3*6)+(2*8)+(1*5)=68
68 % 10 = 8
So 1326-85-8 is a valid CAS Registry Number.
