109776-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109776-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109776-41:
(8*1)+(7*0)+(6*9)+(5*7)+(4*7)+(3*6)+(2*4)+(1*1)=152
152 % 10 = 2
So 109776-41-2 is a valid CAS Registry Number.
