119927-15-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119927-15-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,2 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119927-15:
(8*1)+(7*1)+(6*9)+(5*9)+(4*2)+(3*7)+(2*1)+(1*5)=150
150 % 10 = 0
So 119927-15-0 is a valid CAS Registry Number.
