Check Digit Verification of cas no
The CAS Registry Mumber 100719-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,7,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100719-20:
(8*1)+(7*0)+(6*0)+(5*7)+(4*1)+(3*9)+(2*2)+(1*0)=78
78 % 10 = 8
So 100719-20-8 is a valid CAS Registry Number.
