Check Digit Verification of cas no
The CAS Registry Mumber 3702-98-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3702-98:
(6*3)+(5*7)+(4*0)+(3*2)+(2*9)+(1*8)=85
85 % 10 = 5
So 3702-98-5 is a valid CAS Registry Number.
