1329036-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1329036-44-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,9,0,3 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1329036-44:
(9*1)+(8*3)+(7*2)+(6*9)+(5*0)+(4*3)+(3*6)+(2*4)+(1*4)=143
143 % 10 = 3
So 1329036-44-3 is a valid CAS Registry Number.
