93775-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93775-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,7 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93775-08:
(7*9)+(6*3)+(5*7)+(4*7)+(3*5)+(2*0)+(1*8)=167
167 % 10 = 7
So 93775-08-7 is a valid CAS Registry Number.
