308358-15-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 308358-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,3,5 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 308358-15:
(8*3)+(7*0)+(6*8)+(5*3)+(4*5)+(3*8)+(2*1)+(1*5)=138
138 % 10 = 8
So 308358-15-8 is a valid CAS Registry Number.
