1219619-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219619-55-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,6,1 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1219619-55:
(9*1)+(8*2)+(7*1)+(6*9)+(5*6)+(4*1)+(3*9)+(2*5)+(1*5)=162
162 % 10 = 2
So 1219619-55-2 is a valid CAS Registry Number.
