Check Digit Verification of cas no
The CAS Registry Mumber 92802-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,0 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 92802-30:
(7*9)+(6*2)+(5*8)+(4*0)+(3*2)+(2*3)+(1*0)=127
127 % 10 = 7
So 92802-30-7 is a valid CAS Registry Number.
