Check Digit Verification of cas no
The CAS Registry Mumber 119052-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,5 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119052-95:
(8*1)+(7*1)+(6*9)+(5*0)+(4*5)+(3*2)+(2*9)+(1*5)=118
118 % 10 = 8
So 119052-95-8 is a valid CAS Registry Number.
