Check Digit Verification of cas no
The CAS Registry Mumber 1207328-57-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,3,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1207328-57:
(9*1)+(8*2)+(7*0)+(6*7)+(5*3)+(4*2)+(3*8)+(2*5)+(1*7)=131
131 % 10 = 1
So 1207328-57-1 is a valid CAS Registry Number.
