108311-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108311-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 108311-33:
(8*1)+(7*0)+(6*8)+(5*3)+(4*1)+(3*1)+(2*3)+(1*3)=87
87 % 10 = 7
So 108311-33-7 is a valid CAS Registry Number.
