Check Digit Verification of cas no
The CAS Registry Mumber 140870-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140870-76:
(8*1)+(7*4)+(6*0)+(5*8)+(4*7)+(3*0)+(2*7)+(1*6)=124
124 % 10 = 4
So 140870-76-4 is a valid CAS Registry Number.
