Check Digit Verification of cas no
The CAS Registry Mumber 911218-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,1,2,1 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 911218-20:
(8*9)+(7*1)+(6*1)+(5*2)+(4*1)+(3*8)+(2*2)+(1*0)=127
127 % 10 = 7
So 911218-20-7 is a valid CAS Registry Number.
