107699-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107699-41-2 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, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 107699-41:
(8*1)+(7*0)+(6*7)+(5*6)+(4*9)+(3*9)+(2*4)+(1*1)=152
152 % 10 = 2
So 107699-41-2 is a valid CAS Registry Number.
