Check Digit Verification of cas no
The CAS Registry Mumber 156021-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,0,2 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156021-07:
(8*1)+(7*5)+(6*6)+(5*0)+(4*2)+(3*1)+(2*0)+(1*7)=97
97 % 10 = 7
So 156021-07-7 is a valid CAS Registry Number.
