314765-29-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 314765-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,4,7,6 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 314765-29:
(8*3)+(7*1)+(6*4)+(5*7)+(4*6)+(3*5)+(2*2)+(1*9)=142
142 % 10 = 2
So 314765-29-2 is a valid CAS Registry Number.
