Check Digit Verification of cas no
The CAS Registry Mumber 120931-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,3 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120931-47:
(8*1)+(7*2)+(6*0)+(5*9)+(4*3)+(3*1)+(2*4)+(1*7)=97
97 % 10 = 7
So 120931-47-7 is a valid CAS Registry Number.
