108776-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108776-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,7 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108776-06:
(8*1)+(7*0)+(6*8)+(5*7)+(4*7)+(3*6)+(2*0)+(1*6)=143
143 % 10 = 3
So 108776-06-3 is a valid CAS Registry Number.
