Check Digit Verification of cas no
The CAS Registry Mumber 902837-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,8,3 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 902837-67:
(8*9)+(7*0)+(6*2)+(5*8)+(4*3)+(3*7)+(2*6)+(1*7)=176
176 % 10 = 6
So 902837-67-6 is a valid CAS Registry Number.
