308368-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 308368-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,3,6 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 308368-86:
(8*3)+(7*0)+(6*8)+(5*3)+(4*6)+(3*8)+(2*8)+(1*6)=157
157 % 10 = 7
So 308368-86-7 is a valid CAS Registry Number.
