107699-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107699-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 107699-34:
(8*1)+(7*0)+(6*7)+(5*6)+(4*9)+(3*9)+(2*3)+(1*4)=153
153 % 10 = 3
So 107699-34-3 is a valid CAS Registry Number.
