Check Digit Verification of cas no
The CAS Registry Mumber 870284-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,2,8 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 870284-63:
(8*8)+(7*7)+(6*0)+(5*2)+(4*8)+(3*4)+(2*6)+(1*3)=182
182 % 10 = 2
