119623-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119623-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119623-65:
(8*1)+(7*1)+(6*9)+(5*6)+(4*2)+(3*3)+(2*6)+(1*5)=133
133 % 10 = 3
So 119623-65-3 is a valid CAS Registry Number.
