1239615-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239615-22-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1239615-22:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*1)+(3*5)+(2*2)+(1*2)=155
155 % 10 = 5
So 1239615-22-5 is a valid CAS Registry Number.
