Check Digit Verification of cas no
The CAS Registry Mumber 120638-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,3 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120638-25:
(8*1)+(7*2)+(6*0)+(5*6)+(4*3)+(3*8)+(2*2)+(1*5)=97
97 % 10 = 7
So 120638-25-7 is a valid CAS Registry Number.
