Check Digit Verification of cas no
The CAS Registry Mumber 109876-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,7 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109876-20:
(8*1)+(7*0)+(6*9)+(5*8)+(4*7)+(3*6)+(2*2)+(1*0)=152
