Check Digit Verification of cas no
The CAS Registry Mumber 116653-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,5 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116653-45:
(8*1)+(7*1)+(6*6)+(5*6)+(4*5)+(3*3)+(2*4)+(1*5)=123
123 % 10 = 3
So 116653-45-3 is a valid CAS Registry Number.

, p. 193 - 195 (2007/10/02)
(24R)-24,25-Dihydroxyprovitamin D3 was prepared in 33% overall yield by a six-step procedure starting from the Diels-Alder adduct of ergosteryl benzoate and 1,4-dihydrophthalazine-1,4-dione. The yield thus obtained is more than four times as hi
