Check Digit Verification of cas no
The CAS Registry Mumber 3857-03-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3857-03:
(6*3)+(5*8)+(4*5)+(3*7)+(2*0)+(1*3)=102
