Check Digit Verification of cas no
The CAS Registry Mumber 1655-31-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1655-31:
(6*1)+(5*6)+(4*5)+(3*5)+(2*3)+(1*1)=78
78 % 10 = 8
So 1655-31-8 is a valid CAS Registry Number.
