Check Digit Verification of cas no
The CAS Registry Mumber 119825-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119825-89:
(8*1)+(7*1)+(6*9)+(5*8)+(4*2)+(3*5)+(2*8)+(1*9)=157
157 % 10 = 7
So 119825-89-7 is a valid CAS Registry Number.
