Check Digit Verification of cas no
The CAS Registry Mumber 1565868-91-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,5,8,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1565868-91:
(9*1)+(8*5)+(7*6)+(6*5)+(5*8)+(4*6)+(3*8)+(2*9)+(1*1)=228
228 % 10 = 8
So 1565868-91-8 is a valid CAS Registry Number.
