1429879-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1429879-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,8,7 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1429879-75:
(9*1)+(8*4)+(7*2)+(6*9)+(5*8)+(4*7)+(3*9)+(2*7)+(1*5)=223
223 % 10 = 3
So 1429879-75-3 is a valid CAS Registry Number.
