Check Digit Verification of cas no
The CAS Registry Mumber 120851-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,5 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120851-72:
(8*1)+(7*2)+(6*0)+(5*8)+(4*5)+(3*1)+(2*7)+(1*2)=101
101 % 10 = 1
So 120851-72-1 is a valid CAS Registry Number.
