1229442-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1229442-76-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,4,4 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1229442-76:
(9*1)+(8*2)+(7*2)+(6*9)+(5*4)+(4*4)+(3*2)+(2*7)+(1*6)=155
155 % 10 = 5
So 1229442-76-5 is a valid CAS Registry Number.
