119337-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119337-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,3 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119337-63:
(8*1)+(7*1)+(6*9)+(5*3)+(4*3)+(3*7)+(2*6)+(1*3)=132
132 % 10 = 2
So 119337-63-2 is a valid CAS Registry Number.
